Which of the following is a clinical indication for bone mass measurement according to the Bone Mass Measurement Act?

• A. Individuals performing regular exercise
• B. Women who have had children
• C. Individuals receiving long-term steroid therapy
• D. Younger men without risk factors

Answer: (C)

The correct answer identifies individuals receiving long-term steroid therapy as a clinical indication for bone mass measurement according to the Bone Mass Measurement Act. This is significant because long-term steroid use can lead to secondary osteoporosis, which increases the risk of fractures. Corticosteroids, frequently prescribed for various conditions such as autoimmune disorders or chronic inflammation, can negatively affect bone density and calcium metabolism. Therefore, measuring bone mass in these individuals is crucial for assessing their risk of osteoporosis and taking appropriate preventive measures.

The other choices lack a direct clinical association with increased osteoporosis risk in the context of bone mass measurement. Engaging in regular exercise can promote bone health but does not specifically indicate the need for measurement. Similarly, while women who have had children may experience changes in bone density, it is not a more pressing concern for measuring bone mass than those on long-term steroid therapy. Lastly, younger men without risk factors typically do not necessitate bone mass measurement unless specific risk-related criteria apply, making them less of a priority compared to the effects of steroid therapy on bone density.
